MEMBRANE TYPE LEVEL SWITCH

The DK’s Membrane Level Sensor is a simple and economical instrument suitable for the minimum and maximum level control
inside silos or hoppers that contain non sticky materials, powders or granules like rice, corns, plastics, coffee, sand, lime,
etc.
A membrane level sensor provides level indication by detecting pressure applied by the bulk material to the sensing
membrane. The unit is installed to a vessel wall so that the membrane is exposed to the material to be sensed. As
material contacts the membrane, a force is exerted through the diaphragm to a pressure plate within the level
sensor. Physical deflection of the pressure plate actuates an internal micro switch for signaling alarms, lights or PLC
inputs. When material recedes from the membrane, a light duty spring returns the pressure plate and internal switch
back to their original positions. Humidity and temperature variations do not affect working; the membrane is collision
and vibration proof.
